SPECIFICATION formingpartvof Letters Patent No. 722,492, dated March 10, 1903. Original application filed January 21, 1902I Serial No. 90,637. Divided and `this application filed May 28. 1902. Serial Vllo-109,380.

(No model.)

To a/ZZ whom it may concern:

Be it known that I, FRANK CLAUS, a subject of the Emperor of Germany, residin gat Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Clutches, of which the following is a specification.

My invention relates to improvements in clutches, and is more particularly designed for use in connection with power-transmitting devices-such, for instance, as that type shown and described in my pending application, tiled January 2l, 1902, Serial No. 90,637, from which this application has been divided. It will be understood, however, that the invention herein described is not necessarily limited to devices of the particular type above mentioned, as the same may be employed for the purpose of transmitting motion either from reciprocating or rotary prime movers, as the case may require.

In illustrating the application of my invention I have shown the same applied to a de-V vice for transmitting a reciprocating motion into a rotary motion, the same being thedevice above referred to as forming the subjectmatter of a prior invention.

Referring to the' accompanying drawings, Figure l illustrates a plan view of a powertransmitting device employing.r my improved clutches. Fig. 2 is a front elevation of the same. Fig. 3 represents a vertical section of one of the clutches, taken on a line 3 3 of Fig. 4:. Fig. Ltillustrates a horizontal section of the clutch, taken on line 4 4 of Fig. 3. Fig. 5 shows a detached perspective of a portion of the split ring and toggle-levers, together withV a portion of the slidable bar for operating the toggles; and Figs. 6 and 7 illustrate diagrammatic views of the toggle-levers in diierent positions.

In order to illustrate the manner in which the clutches forming the subject-matter of this invention are used, I have shown in connection therewith the mechanical devices of the pending application above referred to and shall describe their use in connection with such mechanism.

Referring to the reference-letters of the drawings, A represents a reciprocating bar which may be connected to any reciprocating prime mover-much, for instance, as the piston of a steam-engine or other reciprocating motive power. This bar is provided above and below with racks A' and A2, which engage pinions B and B2, loosely supported upon shafts B11 and B12. Each of these pinions is provided with a hub b, through which passes a sliding bar C, which is united to a grooved collar D, loosely supported upon the shaft supporting the pinions. The collar D is operated by a lever E, having a bifurcated end inclosing the collar and pins c c adapted to the groove thereof. The lever E is fulcrumed at E' and is connected to a notched operating-plate E2, provided with an operating finger-piece E3. 'Ihe plate E2 is provided with three notches e, e2, and e3, which are caused to enga-ge the edge of a plate F to hold the lever E in position by means of a spiral spring S. The lower pinion B2, which is loosely mounted on a shaft B12, has a simi* Ylarly-arranged collar D, and the connecting parts are identical with those just described and are indicated by similar letters of reference.

In the rear of the pinions B and B2 are cupshaped disks G G, each being secured to its respective shaft by means ot set-screws g g.

`The shafts B11'and B12 are provided, respectively, with gear-wheels H and H', which engage a broad pinion I, mounted upon a shaft J, provided with a ily-wheel K.

Arranged between the pinion B' and the disk G and between the pinion B2 and lower disk G is the clutch mechanism by which the pinions may be brought into engagement with the disks to operate them in either direction, or, if desired, by moving the levers E to the proper position one or both of the clutches may be thrown out of action. As both of the clutches are identical in construction, a description of one will sufce for the other, and similar letters of reference will be employed to designate similar parts in both cases.

The hub b of each of the pinions is slotted at b to receive the sliding bar C, which is slightly concave on its upper surface, as

shown at c, to permit the lever C12 to pass from one position to the other without distending roo the ring G. The sliding bar is provided near its end with an inclined slot C to receive a pin C2, which is projected from a lever C12, hinged to toggle-levers C15 and C14.

Closely engaging the inner wall of the cupped disk G is a split ring G', which has rounded ends adapted to fit concave-surfaceming sockets in the toggle-levers C13 and the ends of the split ring are caused to eln- Abrace the inner Wall of the cupped disk by means of an elliptic spring S, which is held by'asupport 012 on the hub b and bears against a cross-piece cl3, arranged upon the pin 014, which connects the levers C12, C13, and C14.

When the machine is in operation, each of the levers E is operated so that the notch e2is in engagement with the plate F, as shown in Fig. l, and then the clutches are thrown out of action. If, however, the lever E be moved so that the notch e3 is in engagement with the plate F, then the levers C12, C13, and C14 will assumethe position shown in the diagram Fig. 5, and a movement of the bar A will cause the rotatable parts to move in the direction indicated by the full arrows shown in Fig. l. If the lever E be shifted kso that the notch e is in engagement with the plate F, the levers C12, C13, and C14 will assume the position shown in the diagram Fig. 6, and the rotatable parts of the device by a movement of the barA will turn in the direction indicated by the dotted arrows in Fig. l.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. Aclutch for power-transmitting devices comprising a disk fixedly secured to a shaft, and a hub loose upon the shaft, a slidable bar journaled in the hub, provided with an inclined slot, a split ring engaging the inner Wall of the disk, toggle-levers, engaging the ends of the ring, a lever for operating the toggles, one end of which is guided in the inclined slot, and means for operating the slidable bar to cause the toggles to bind with one or the other ends of the ring, substantially as specied.
